Fisher Discriminant Analysis Model of Drilling Downhole Accidents and its Application

Abstract:

Based on Fisher discriminant theory, the Fisher discriminant analysis model (FDA) was established for predicting the possibility of drilling downhole accidents. Six factors such as WOB、pump pressure、pump flow、running speed、ROPand torque were selected as the discriminant factors of the FDA mode. A series of data from drilling downhole accidents were taken as the training samples, and then some practical engineering datas were used to verify this mode. It was showed that FDA model is one of simple and accurate method in solving the prediction of drilling downhole accidents.
